The present invention relates hro'adly to supports; and more particulh'rly' to supports adapted for cooperation with a structuralmember for the securing in position ofcon '5 d'uits and the like; The terms structural member and conduit are henein' used? ge nerica lly as wordsoi? definition and not as words of limitation;

It has heretofore-"Been proposed in the m to which this invention relates toprovide conduit supports adapted to; be: clamped inposition on as structural memher for" holtling a conduit in a position-s11 stantiallypara'llel to one of the edges thereof": Ithas'alsabeenproposed to provide supports, adaptedtosecur'econduits at to one of" the faces of a: structural support, such; for example; as an angle iron 01: the like;

In the accompanying diiawings; for the purpose of illustrating my invention, I have shown a structural memberin" the; form of; an angle iron 2", the angle iron heing soiv mounted as co-receive the conduit support on" itsverticalfangs-3 It will be understood, however; that other forms of structural memhers may be utilized; and that the invention is not, liinithd inconnection with the characteristics or positioning of the structural member.

The improved suppont constructed in accordhnce with the present inventioncom-- prises'a clamp member and a clanip mom:- her 13- adapted todoe positioned on oppositesi'des oi the verticaiflange oi? the supporting member. hen so positioned the conduit engaging-jawed andb' onthe-clam-p mem'hersandfB; respectirely; lie in substantially the plane of the vertical flange ofthe' structuralmemloer. and in suchposition as to receive a= section: of conduit G therebetween: It will be noted} that the jaw a isoiisetwith respect to thennainbod? of'theclamp A, and that the b"- is' offset with respect tot-he main 85 liodiyoi the-clamp B; thejaws'being'oiiset in oppositedirections, whereby they assume overlapping-'reiationship when the support is positioned with respect to a structural meniher. 99;

I The clamp *B is formed 'with spaced teeth 4 and 5; anc f the" clamp A is fornied with a tooth 6; of: which teethareadapted to firmly engage the structural member and prevent" slipping of the support. Preferthe tooth comprisesa hardened steel insert, as has been heretoforeproposed" in the art, although such a construction isnot essential. The tooth- 6" preferably lies substantially' intermediatetheplanes of contact mg v such as to bring the. jaws a and b closer to 1 one toward tion-therebetween.

of the teeth 4 and 5, so as to provide a threepoint grip with'the structural member.

The clamp members are conveniently drawn together by a bolt 7 extending therethrough substantially normal to the edge of the flange 3, and substantially parallel to the axis of the. conduit positioned between the jaws a and b. The clamp B may have its outer'face constructed, as clearly indicated in Figure 4, to provide substantially verti cally extending ridges 8 'betweenwhich the head 9 of the bolt 7 may engage to prevent turning thereof nut 10 into position. i j t In order that the drawing of the clamp members into gripping relationship with the structuralmember will also effect gripe jection 13 having a concave recess with a adapted to cooperate with tapered wall 14 the inclined face rangement,

By reasonofthis ardrawing together of the, clamp members will cause the projection 13 to ridedownon the lug 11, with the result. that theinclined faces 12 and '14 will tend to bring the jaws a and b closer together. 7 s V For supplementing this rotational tendency, the lower end of, the clamp Bhas an in: clined face 15, while the lowerend of the clamp A carries a projection 16having an inclined face 17 for cooperation with the inclined face 15. The inclination of these faces issuch that drawing together 10f the clamp members will'also effect relative rota- This relative rotation of the respective clamp members is in thedirection indicated by .By reason of the construction disclosed there is provided or holding a conduit at substantially} right angles to the edge of a structural member.

This, constitutes one ofthe advantages of the present invention. H Another advantage of the present invention arises from the provision of a support comprising clamping members interconnected'by a single clamping means, suchas a bolt,

and effective during the clamping operation c0 f and e fiecting relative rotational movement or drawing the clamping members together therebetween. I r

Still other advantages of the invention arise from theprovisionof. a conduit support having clamping means, :gand having during the tightening of the faces thereon,
